Check validity of email address
In the email address: USER@HOST.DOMAIN
USER can be a literal e.g. "John. Bloggs:" (No further rules for literals so I have allowed adjacent punctuation characters)
HOST.DOMAIN can be an IP address e.g. [22.214.171.124]
Otherwise neither USER nor HOST is allowed to contain the reserved charactes: ()<>\,;:" space @ but may contain all other printable ACII characters.
It is assumed that no two VALID punctuations may be adjacent except when a literal or IP is involved.
DOMAIN must be either a 3 letter domain code or a 2 letter country code or the word 'localdomain'.
Note that a DOMAIN organisation is not concerned with how a HOST organisation allots USER names except that reserved characters have a meaning at DOMAIN level.
Interpreting the rules to the letter "sam@westpark"@juno.com is a valid email address but we do not allow it on the assumption that host 'juno' (which controls its own user names) would not be so careless as to allow '@' in user names.
